This entry by Jon Udell is rather disappointing, mostly because it sits on the false presumption that choosing and using an API to update a blog with is a binary decision. Far from it, the Blogger, LiveJournal and metaWeblogAPI have co-existed for quite some time, with clients supporting all of them. If the Pie project succeeds in producing a new API, that will not mean the immediate removal of those APIs, nor will all the current software magically break the instant the RFC is approved.
On the other hand, I was gratified to read:
Were there no legacy to consider, I'd much prefer the new approach. [Jon Udell]
I would like to inject that RESTLog isn't the EchoAPI, but I am glad to have RESTLog be one of the EchoAPIs inspirations.
